An Electric Brunswick Cortez?

[Uncle Vanya]

It does appear that someone has heavily re-worked the original RPA 3-A.

That RPA box should not have either of the excresences, the stack or the transformer.

I've owned a P-14, but have not yet had an Electrola Cromwell. Are there substantial differences betweern the amplifiers used in these two machines?

I have put back somewhere one of those rather bizzare Brunswick PR-6 machines. An electronic panatrope with an electric pickup, a Radiola 25, and a strange amplifier, an RPA-6, in what seems to be the same case as was used for the RPA-3A,, except instead of being essentially a Uni-Rectron with an added '99 as a voltage ampifier, the RPA-6 is electrically a Duo-Rectron with an added 171 power amplifier stage substituted for the voltage regulator tube. The PR-6 uses batteries to light the filaments, but the light socket for B+ voltage. It is fitted with an RCA 100 style speaker.
